Method Summary

CoordinateWorld	mapWindowCoordinateToWorldCoordinate_(CoordinateCartesianAbsolute coordinateWindow) Translates a window coordinate in pixels to a world coordinate in latitude and longitude.
CoordinateCartesianAbsolute	mapWorldCoordinateToWindowCoordinate_(CoordinateWorld coordinateWorld) Translates a world coordinate in latitude and longitude to a window coordinate in pixels.
double	mapWorldDistanceToWindowDistance_(Latitude distance) Computes a world distance in latitude to a window distance in pixels.

Method Detail

mapWindowCoordinateToWorldCoordinate_

CoordinateWorld mapWindowCoordinateToWorldCoordinate_(CoordinateCartesianAbsolute coordinateWindow)

Translates a window coordinate in pixels to a world coordinate in latitude and longitude.

Parameters:

coordinateWindow - - the window coordinate

Returns:

the world coordinate, or null if the window coordinate is off the world

mapWorldCoordinateToWindowCoordinate_

CoordinateCartesianAbsolute mapWorldCoordinateToWindowCoordinate_(CoordinateWorld coordinateWorld)

Translates a world coordinate in latitude and longitude to a window coordinate in pixels.

Parameters:

coordinateWorld - - the world coordinate

Returns:

the window coordinate, or null if the world coordinate is off the window

mapWorldDistanceToWindowDistance_

double mapWorldDistanceToWindowDistance_(Latitude distance)

Computes a world distance in latitude to a window distance in pixels.

Parameters:

distance - - the world distance

Returns:

the pixel distance
